In-vivo comparison of the Ni-free steel X13CrMnMoN18-14-3 and titanium alloy implants in rabbit femora - A promising steel for orthopedic surgery.

A variety of metallic biomaterials is used for fracture fixation. Allergic reactions towards nickel-containing steels urge the need for alternatives. The present study investigated the suitability of the nickel-free stainless steel P2000 in comparison to titanium alloy implants for bone surgical applications in a rabbit femora defect model.

P2000 - A high-nitrogen austenitic steel for application in bone surgery.

Optimal treatment of bone fractures with minimal complications requires implant alloys that combine high strength with high ductility. Today, TiAl6V4 titanium and 316L steel are the most applied alloys in bone surgery, whereas both share advantages and disadvantages. The nickel-free, high-nitrogen austenitic steel X13CrMnMoN18-14-3 (1.
